Lost Rivers

Groups of urban explorers act in a quite secretive way. They go looking for rivers that, even if we can’t see them and they’ve been forgotten, they still flow underneath our cities. The documentary film Lost Rivers lead us along the rivers of six cities. We will see how the hunters of lost underground waterways act crossing tunnels and lairs (Saint Pierre River in Montreal); how to exploit the rivers to recycle rainwater without overloading the sewage system (from Toronto with the Garrison Creek to London with the Tyburn); how the little city of Yonkers has changed its local economy reactivating the river (Saw Mill River in New York); how instead of making a overhead freeway it was decided to requalify the area going back to the origins (Cheonggyechon River in Seoul); we will follow the adventures in the underground of Brescia, once rich in mills, tanneries and wash houses, where they’re trying to improve an extraordinary historical patrimony (with more than 13 rivers, such as Bova-Celato, that flows hidden in the center).
